Concentrated AI execution — SEIS Investment

What Build46 does

AI has collapsed the time of building software. Build46 combines AI execution with expert distribution, scaling commercial SaaS and products.

We concurrently build and scale products within niche markets and audiences, validated with data, built with AI tooling then either scaled or shut down under a strict go/no-go process.

What we're building

Agnostic to market, we're concentrating on Business and Consumer SaaS / apps SaaS, AI core or Agentic products over 18+ months.

20+ products

Building 20+ products; niches that can support 200K to 1M+ users globally.

Mid-sized software

Software only — no human or manual processes. 100% automated, scalable builds.

Our build process

We concurrently build and scale products within niche markets and audiences.

1. Validate idea with data

Governed by a strict go/no-go point-based decision tree.

2. Create distribution

Repeatable methods to drive waitlist and pre-paid signups.

3. Build a minimum sellable product

Using AI tooling, we condense build time to a saleable service or product.

4. Ramp up distribution & iterations

Growth flywheels, partners and routes for continued growth.

Our growth process: we concurrently build with an efficient scale-or-kill decision — from idea launch through distribution and product-market fit to sale/exit, keep & grow ARR, or archive.
